Microsoft DirectX 8.1 (C++)

IFilterInfo::get_Filter

The get_Filter method retrieves the IBaseFilter interface of the filter.

Syntax

HRESULT get_Filter(
  IUnknown **ppUnk
);

Parameters

ppUnk

[out, retval] Address of a pointer to the IBaseFilter interface of the filter represented by IFilterInfo::FindPin.

Return Value

Returns an HRESULT value.

Remarks

The object that implements IFilterInfo is a wrapper and is not the same COM object as the filter itself. Thus a call to IFilterInfo::QueryInterface for IBaseFilter will fail. The IFilterInfo::get_Filter method enables an application to obtain the filter object itself. This method is exposed for use by Automation clients and is not expected to be used by C or C++ applications because of performance limitations.
